Joking aside, I bought this set for some graphics work and I'm pretty impressed.It has quick release to quickly open and close the radius the dial for finer adjusting.It rotates smoothly when used so you get a nice smooth continuous circle.The main point which I bought it for is the pen adaptor which holds my graphics pens nicely.All in all, a nicely made piece of kit that does the job well.

Only grumble, lack of instructions. OK, it's fairly simple once you've fiddled around with it but it did take me a little while to work out all the various attachments and how to switch them around.

I brought this product to help keep my dad's old, but very vintage, geometry set preserved.

Sadly, the first one arrived damaged such that one of the hinges on the parent compass was damaged. Upon returning it and being issued a replacement (which arrived very quickly thanks to Amazon's exemplary customer service as per usual), I'm very impressed with the quality of the set. Thankfully, I can safe-keep my dad's old set and 'wreck' this one now!

I was anxious at first thinking that maybe the structure of the set would be all-plastic, but it is actually mostly metal. They've used plastic as "joints" to each "bone" or "arm" of the compasses. And it's also worth noting that you don't need to use a screw driver to tighten the joints in any of these compasses, it's all done by thumb.

I've always preferred thumb-wheel compasses over the conventional ones in that they are more accurate and they remain fixed on that measurement (as opposed to the conventional ones where no matter how much you tighten that screw on the joint, it would still cause the compass to lose the measurement when you draw and it could also damage its accuracy for future drawings).

Overall, I'm very impressed with it and I think it'd make an excellent companion to anyone involved in maths.

This is a great drawing set and very cheap. It is well engineered and will be very accurate in use. If you're looking for a bargain this is it. Don't let the cheap price put you off, under £10 and free delivery, this is an excellent drawing set which will last years.

I am really happy with this set! Which is a vast improvement from the student maths set I was using!!!

So far it all seems sturdy and ease to use. My only initial issue is that the case insert doesn't allow for storing anything with the pen attachment on. And I don't want to take the pen attachment off every single time I pop the case in my bag. If the case was a little more versatile I would be thrilled. But as it is I need to find some other sort of case for storing the set to bring with me in my bag.

The " Thumb Wheel " and its " Quick Release " help a lot and make changes in radius really convenient and also hold the size firm and fixed , which make it a joy to use ! Average size for most purposes for a wide variety of usage . Really really good .

good set - only thing I think they got wrong - is having to remove the pin completely to switch components - the one I had, a while back, all you had to do was loosen, and the parts came apart, so easier, faster, and less likely to lose the very small pins.....

Very high quality set. Easy to use and comes with all the extras you need.

Took me a minute to work out the extension arm was not actually a separate bar compass it attaches to the main compass after you remove one of the legs. If you need instructions you can email helix and they send them out. Everything fits together pretty well and while its all plastic its high quality so not a problem. You get extra screws and leads with it as well so its very handy.
